Description
Write signal from the pipeline and resynchronization logic.
DLL delay control from the top-level design to shift the CQ by a
nominal 90 degrees.
capture_clock
Output
Capture clocks (CQ into soft logic) to the pipeline and
resynchronization logic.
captured_data
35:0
Output
Captured data—data after the IO to pipeline and
resynchronization logic.
Table 3–6 shows the datapath.
